Yeah, casting would be a little overkill for the project, though if you made a rubber mold of the wood base, it would be pretty easy.  My concern would be that the rubber would pick up the detail of the wood grain.

I was thinking more about cutting pieces of 1/2" black acrylic, gluing, routing, and polishing.

I like this idea, PB.  Should be a beautiful, high gloss base.

Cheers,

Yeow! Don't call me when you need those electrolytics replaced.

Yeah, he mentions in the text that it's a one shot deal but, then again, it's a Cmoy with $10 worth of parts.  I bet it mostly sits on a shelf as a display piece.

I think Woo Audio's Fireflies may have borrowed the idea:

Okay, off topic a bit but your post reminds me of this Cmoy project from a few years ago.

Even pre casting thats a work of art!

Without a doubt - much more a design exercise than audio

I was thinking along the lines of using some melamine faced mdf and hot glue to make a dam the shape of the surround so the base would be cast as one piece.  Just the enclosure not the whole thing!!

No problem to sand out any marks and get back to crystal clear. Go through the grades and compounds and finish off with some brasso metal polish or swirl remover.

That could certainly work on the outside faces but I wonder how easy that would be on the inside faces.

A angle headed die grinder fitted with a polishing head would make short work of it  ;)

Edit, the best thing to use for moulding such surfaces is glass, you can get a perfect surface finish no sanding then clear coating. Its how I made the carbon fibre top plate on my Crack.
